一、计步器和计数器
- (void)creatStepper{
//步进器 、计数器
//事件驱动型
UIStepper *stepper = [[UIStepper alloc] initWithFrame:CGRectMake(100, 100, 100, 50)];
//设置默认色调
//stepper.tintColor = [UIColor redColor];
//设置最小值 默认是0
stepper.minimumValue = 0;
//设置最大值 默认是100
stepper.maximumValue = 1000;
//设置步长 默认是1
stepper.stepValue = 10;
//设置长按 之后是否可以连续触发 函数
/*
YES:长按的时候 连续 触发调用stepperClick:
NO:长按的时候 的时候 stepperClick:最后松手调用一次
*/
stepper.continuous = YES;
//长按的时候是否可以 反复修改stepper的值
/*
YES：可以连续的修改 值
NO： 不去连续改值 长按的时候只改一次
*/
stepper.autorepeat = YES;
//增加事件
[stepper addTarget:self action:@selector(stepperClick:) forControlEvents:UIControlEventValueChanged];
[self.view addSubview:stepper];
[stepper release];
}
- (void)stepperClick:(UIStepper *)stepper {
NSLog(@"value:%f",stepper.value);//打印当前的值
}
二、操作表单
需要遵守协议
@interface ViewController7 () <UIActionSheetDelegate>
@end
- (void)creatButton{
UIButton *button = [MyControl creatButtonWithFrame:CGRectMake(110, 100, 100, 50) target:self sel:@selector(btnClick:) tag:101 image:nil title:@"分享"];
[self.view addSubview:button];
}
- (void)btnClick:(UIButton *)button {
//操作表单
/*
destructiveButtonTitle: 把一些危险的操作 按钮 写在这里 会显示红色
*/
UIActionSheet *sheet = [[UIActionSheet alloc] initWithTitle:@"分享" delegate:self cancelButtonTitle:@"取消" destructiveButtonTitle:@"危险操作按钮" otherButtonTitles:@"短信分享",@"朋友圈分享",@"QQ分享" ,nil];
//从self.view上弹出
[sheet showInView:self.view];
[sheet release];
}
#pragma mark - UIActionSheetDelegate
//当点击actionSheet的按钮的时候 通知代理调用处理
- (void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex {
//索引值 从上至下 从0开始
NSLog(@"index:%ld",buttonIndex);
}
三、分段控制器和时间驱动器
- (void)creatSegmentedControl{
//分段控制器
//事件驱动型
NSArray *titles = @[@"小红",@"小黄",@"屎壳郎"];
UISegmentedControl *seg = [[UISegmentedControl alloc] initWithItems:titles];
seg.frame = CGRectMake(10, 100, 300, 30);
//设置属性
//设置默认选中的分段
seg.selectedSegmentIndex = 0;
/*
//增加标题分段
- (void)insertSegmentWithTitle:(NSString *)title atIndex:(NSUInteger)segment animated:(BOOL)animated;
//增加图片分段
- (void)insertSegmentWithImage:(UIImage *)image atIndex:(NSUInteger)segment animated:(BOOL)animated;
//删除指定
- (void)removeSegmentAtIndex:(NSUInteger)segment animated:(BOOL)animated;
//删除所有
- (void)removeAllSegments;
*/
//增加图片分段 显示原始图片
[seg insertSegmentWithImage:[[UIImage imageNamed:@"002"] imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal] atIndex:1 animated:YES];
//禁用 指定分段
[seg setEnabled:NO forSegmentAtIndex:3];
//设置指定分段宽度0 自动设置设置宽
//[seg setWidth:40 forSegmentAtIndex:0];
//设置tintColor
seg.tintColor = [UIColor redColor];
//设置背景图片 竖屏
[seg setBackgroundImage:[UIImage imageNamed:@"toolBar"] forState:UIControlStateNormal barMetrics:UIBarMetricsDefault];
//设置 内容偏移量
//width >0 右偏移 height >0 向下偏移
[seg setContentOffset:CGSizeMake(5, 5) forSegmentAtIndex:0];
//更改属性字符串(修改内容字符串的颜色和大小)
NSDictionary *dict = @{NSFontAttributeName:[UIFont systemFontOfSize:20],NSForegroundColorAttributeName:[UIColor yellowColor]};
[seg setTitleTextAttributes:dict forState:UIControlStateNormal];
//增加事件 点击分段值改变触发
[seg addTarget:self action:@selector(segClick:) forControlEvents:UIControlEventValueChanged];
[self.view addSubview:seg];
[seg release];
}
- (void)segClick:(UISegmentedControl *)seg {
//seg.selectedSegmentIndex 被点击的分段索引
//[seg titleForSegmentAtIndex:seg.selectedSegmentIndex]获取分段的标题
NSLog(@"index:%ld title:%@",seg.selectedSegmentIndex,[seg titleForSegmentAtIndex:seg.selectedSegmentIndex]);
}
四、警告视图
遵守协议<UIAlertViewDelegate>
@interface ViewController8 ()<UIAlertViewDelegate>
@end
- (void)creatAlertView{
//警告视图
NSArray *titles = @[@"普通",@"用户",@"密码",@"登录注册"];
for (NSInteger i = 0; i < titles.count; i++) {
UIButton *button = [MyControl creatButtonWithFrame:CGRectMake(110, 100+40*i, 100, 30) target:self sel:@selector(btnClick:) tag:101+i image:nil title:titles[i]];
[self.view addSubview:button];
}
}
- (void)btnClick:(UIButton *)button {
//四种不同风格的警告视图
/*
UIAlertViewStyleDefault = 0,
UIAlertViewStyleSecureTextInput,
UIAlertViewStylePlainTextInput,
UIAlertViewStyleLoginAndPasswordInput
*/
switch (button.tag) {
case 101://普通
{
UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"警告" message:@"非法入侵" delegate:self cancelButtonTitle:@"取消" otherButtonTitles:@"确定", nil];
//设置类型
alertView.alertViewStyle = UIAlertViewStyleDefault;
alertView.tag = 201;
[alertView show];
[alertView release];
}
break;
case 102://用户
{
UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"角色名称" message:nil delegate:self cancelButtonTitle:@"取消" otherButtonTitles:@"确定", nil];
//设置类型
alertView.alertViewStyle = UIAlertViewStylePlainTextInput;
alertView.tag = 202;
[alertView show];
[alertView release];
}
break;
case 103://密码
{
UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"密码" message:nil delegate:self cancelButtonTitle:@"取消" otherButtonTitles:@"确定", nil];
//设置类型
alertView.alertViewStyle = UIAlertViewStyleSecureTextInput;
alertView.tag = 203;
[alertView show];
[alertView release];
}
break;
case 104://登录注册
{
UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"登录" message:nil delegate:self cancelButtonTitle:@"登录" otherButtonTitles:@"注册", nil];
//设置类型
alertView.alertViewStyle = UIAlertViewStyleLoginAndPasswordInput;
alertView.tag = 204;
[alertView show];
[alertView release];
}
break;
default:
break;
}
}
#pragma mark - 代理方法
- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex {
//通过tag区分alertView
//通过类型也区分 不同类型的alertView
switch (alertView.alertViewStyle) {
case UIAlertViewStyleDefault:
{
NSLog(@"普通警告视图：%ld",buttonIndex);
}
break;
case UIAlertViewStylePlainTextInput:
{
//获取 alertView中textField
UITextField *text1 = [alertView textFieldAtIndex:0];
NSLog(@"用户:%@",text1.text);
}
break;
case UIAlertViewStyleSecureTextInput:
{
//获取 alertView中textField
UITextField *text1 = [alertView textFieldAtIndex:0];
NSLog(@"密码:%@",text1.text);
}
break;
case UIAlertViewStyleLoginAndPasswordInput:
{
UITextField *text1 = [alertView textFieldAtIndex:0];
NSLog(@"用户名:%@",text1.text);
UITextField *text2 = [alertView textFieldAtIndex:1];
NSLog(@"密码:%@",text2.text);
}
break;
default:
break;
}
}
五、菊花
- (void)creatAIV{
//UIActivityIndicatorView 活动指示器 -》菊花/风火轮
//普通的视图
/*
UIActivityIndicatorViewStyleWhiteLarge,//大白
UIActivityIndicatorViewStyleWhite,//小白
UIActivityIndicatorViewStyleGray,//小灰
*/
UIActivityIndicatorView *view = [[UIActivityIndicatorView alloc] initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleWhiteLarge];
view.frame = CGRectMake(100, 100, 100, 100);
//放到中间
view.center = self.view.center;
//默认必须转动 才显示
//view.hidesWhenStopped = NO; 默认 停止转动隐藏
//改变 转动的颜色
view.color = [UIColor redColor];
[view startAnimating];
//2s之后 停止菊花转动
//withObject:传得就是 click:的参数
[self performSelector:@selector(click:) withObject:view afterDelay:2];
//打开 状态栏上的系统自带的网络小菊花
[UIApplication sharedApplication].networkActivityIndicatorVisible = YES;
[self.view addSubview:view];
[view release];
}
- (void)click:(UIActivityIndicatorView *)view {
if (view.isAnimating) {
[view stopAnimating];//停止转动
[UIApplication sharedApplication].networkActivityIndicatorVisible = NO;//关闭
}
}
六、文本输入框
- (void)creatUITextView{
//UITextField 只能输入一行
//iOS7之后 滚动视图粘到带导航的视图上时，滚动视图的内容会自动向下偏移64像素,
//如果不想自动偏移 那么我们需要取消导航的影响
self.automaticallyAdjustsScrollViewInsets = NO;
//或者
//self.edgesForExtendedLayout = UIRectEdgeNone;
//UITextView //文本输入 多行 (可以滚动)
UITextView *textView = [[UITextView alloc] initWithFrame:CGRectMake(10, 100, 300, 200)];
textView.tag = 101;
//设置背景
textView.backgroundColor = [UIColor orangeColor];
//设置内容
textView.text = @"xxxxxxx小红和小黄有激情xxxxxxx小红和小黄有激情xxxxxxx小红和小黄有激情xxxxxxx小红和小黄有激情xxxxxxx小红和小黄有激情xxxxxxx小红和小黄有激情xxxxxxx小红和小黄有激情xxxxxxx小红和小黄有激情xxxxxxx小红和小黄有激情xxxxxxx小红和小黄有激情xxxxxxx小红和小黄有激情xxxxxxx小红和小黄有激情xxxxxxx小红和小黄有激情xxxxxxx小红和小黄有激情xxxxxxx小红和小黄有激情xxxxxxx小红和小黄有激情xxxxxxx小红和小黄有激情xxxxxxx小红和小黄有激情xxxxxxx小红和小黄有激情xxxxxxx小红和小黄有激情";
//字体颜色
textView.textColor = [UIColor redColor];
//字体大小
textView.font = [UIFont systemFontOfSize:20];
//设置是否可以滚动
//textView.scrollEnabled = NO;
//设置是否可以编辑
//textView.editable = NO;
//设置代理
textView.delegate = self;
[self.view addSubview:textView];
[textView release];
}
//收键盘
- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {
UITextView *text = (UITextView *)[self.view viewWithTag:101];
[text resignFirstResponder];
}
#pragma mark - UITextViewDelegate
//将要进入编辑模式的时候调用
- (BOOL)textViewShouldBeginEditing:(UITextView *)textView {
NSLog(@"%s",__func__);
return YES;//是否可以进入编辑模式
}
//已经进入编辑模式
- (void)textViewDidBeginEditing:(UITextView *)textView {
NSLog(@"%s",__func__);
}
//将要退出编辑模式调用
//决定是否可以结束编辑模式
- (BOOL)textViewShouldEndEditing:(UITextView *)textView {
NSLog(@"%s",__func__);
return YES;
}
//已经退出编辑模式
- (void)textViewDidEndEditing:(UITextView *)textView {
NSLog(@"%s",__func__);
}
//已经修改内容就会调用
//修改的时候一直调用
- (void)textViewDidChange:(UITextView *)textView {
NSLog(@"%s",__func__);
}
//只要修改 或者 选中 就会调用
- (void)textViewDidChangeSelection:(UITextView *)textView {
NSLog(@"%s",__func__);
}
//将要把内容 输入到 textView 的时候调用
//YES 表示可以输入到textView中 NO 不可以
//range 光标的位置 text ：将要输入的内容
- (BOOL)textView:(UITextView *)textView shouldChangeTextInRange:(NSRange)range replacementText:(NSString *)text {
NSLog(@"range:%@ text:%@",NSStringFromRange(range),text);
return YES;
}
八、下载进度条
- (void)creatProgressView{
//进度条 下载进度等
UIProgressView *proView = [[UIProgressView alloc] initWithFrame:CGRectMake(10, 100, 300, 30)];
//更改 progress就可以显示进度
//proView.progress = 0.5;
//更改轨道颜色
// proView.progressTintColor = [UIColor redColor];
//进度颜色
// proView.trackTintColor = [UIColor greenColor];
//模拟下载
//启动一个定时器 每个1s 更改下载进度
//userInfo 给定时器 触发的 函数传入一个对象 内部timer.userInfo获取
[NSTimer scheduledTimerWithTimeInterval:1 target:self selector:@selector(timerClick:) userInfo:proView repeats:YES];
[self.view addSubview: proView];
[proView release];
}
- (void)timerClick:(NSTimer *)timer {
//获取传入的值
UIProgressView *view = timer.userInfo;
if (view.progress < 1.0) {
view.progress += 0.1;
}else {
//下载完成 终止定时器
[timer invalidate];
}
}
九、滑动条

UISlider *slider = [[UISlider alloc] initWithFrame:CGRectMake(100, 200, 200, 30)];
//设置最小值
slider.minimumValue = 0;
//设置最大值
slider.maximumValue = 1;//默认是1
//设置轨道颜色
slider.minimumTrackTintColor = [UIColor redColor];
slider.maximumTrackTintColor = [UIColor yellowColor];
//设置 最小值、最大值的图片
slider.minimumValueImage = [UIImage imageNamed:@"003"];
slider.maximumValueImage = [UIImage imageNamed:@"002"];
//设置 小白球的图片
[slider setThumbImage:[UIImage imageNamed:@"003"] forState:UIControlStateNormal];//正常状态
[slider setThumbImage:[UIImage imageNamed:@"002"] forState:UIControlStateHighlighted];//高亮状态
//设置 旋转 修改 transform --》旋转 / 翻转 / 缩放
//相对于 最原始的位置旋转-九十度
slider.transform = CGAffineTransformMakeRotation(-M_PI_2);
//长按是否连续触发 事件函数
slider.continuous = YES;//NO长按滑动 只触发一次 YES连续触发函数
//增加事件
[slider addTarget:self action:@selector(sliderClick:) forControlEvents:UIControlEventValueChanged];
[self.view addSubview:slider];
[slider release];
}
- (void)sliderClick:(UISlider *)sd {
NSLog(@"sd:%f",sd.value);//打印值
}
十、开关控件
//常见控件 1.普通视图2.事件驱动型控件(一般UIControl的子类)
- (void)creatView {
//开关 1.用设置界面
UISwitch *sw = [[UISwitch alloc] initWithFrame:CGRectMake(0, 100, 200, 50)];

sw.on = YES;
//增加事件
//当 手指 触发小球 开关状态发生改变的时候调用
[sw addTarget:self action:@selector(swClick:) forControlEvents:UIControlEventValueChanged];
[self.view addSubview:sw];
[sw release];
}
//给谁增加的事件 参数就是谁
//当 手指 触发小球 开关状态发生改变的时候调用
